Question

Which longitude has been taken as standard meridian of India and why

Answer 1

Answer:● 82°30'E been selected as the Standard Meridian of India The standard meridian

of India is chosen due to the following reasons:-

1. The longitudinal extent of India is about 30 o for every 1 o of longitude

there is a time difference of one hour. Hence for an interval of 30 o there

is a time difference of nearly two hours between the eastern and the

western most extremity of India. To avoid the confusion of time, 82 o 30’

E longitude has been chosen as the, Standard Meridian

2. There is a general understanding among the countries of the world to

select a Standard Meridian in multiples of 7 ½ o both to the east and

west of the Prime Meridian so that the minimum time difference

between 2 countries is half an hour.

3. The standard meridian of a country should pass through, as far as

possible the middle of a country. 82 o 30’ E longitude passes almost

centrally through India, hence equidistant from the east and west.
